DYEING MACHINE.

Application filed April 19, 1922. Serial No. 555,563.

To all whom it 'may concern Be it known that we, JOHN H. Gines and DoNALD W. GrLns, both residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in a Dyeing Machine, of which the following is a specification.

This invention relates to improvements in yarn dyeing machines and more particularly to improvements in' which skeins of yarn are dyed while held by yarn sticks mounted in inner and outer supporting members.

n such machines, there is usually provided a vat for the dye liquor through which extends a shaft. Mounted on the shaft is a pair of yarn sticks supporting members between which the sticks extend. A similar pair of supporting members is also provided between which a second series of yarn sticks is mounted, the members of the second series lying parallel to and somewhat nearer the shaft than the outer series. The yarn in the skein form is held between corresponding sticks of the inner and outer series, the supporting members being relatively adjustable so as to put a slight tension on the yarn. With the yarn relatively taut,'the shaft with the stick supporting members is then lowered and upon being revolved, the sticks with the yarn thereon are successively immersed in the dye liquor.

One of the objects of this invention is to provide a new and improved means for adjusting the relative positions of the yarn stick supporting members of such a dyeing machine to place tension on the yarn. The adjusting means forming the subject-matter of this application for patent are believed to be a material improvement upen the devices for the purpose included in ourvpatent of the United State-s numbered 1,146,824, dated July 13, 1915, by reason of the advantages hereinafter explained.-

Another object is to provide a new vand improved means for adjusting the tension on the 'yarn in a dyeing machine, the ad justing means being easily operable without the danger of theoperative touching the yarn in position on the sticks.

Still another' object is to provide a new and improved means for adjusting the tension on the yarn in a dyeing machine, the adjusting means being operable to produce a fine adjustment with no danger of enta-ngling the yarn.

- Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed'out in the' course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting' the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the drawings in which we show a preferred form of embodiment of our invention:

Figure 1 is a transverse sectional view of a yarn machine of the type described.

Figure 2 is a longitudinal sectional View of a similar machine.

Figure 3 is a detail view of the parts forming our improved tensioning means.

yWith reference now to the'drawings in which similar reference characters refer to similar parts throughout the several views thereof, the reference character 1 designates a vat for dye liquor, having straight vertical sides 2 and a rounded bottom 3. Mounted in arcuate slots 4r, 4t in the side walls is a shaft 5 suitably counterweighted by means of cables G, 6 which pass over pul leys 7, 7 on a shaft 8, to be attached to weights 9. 9. By this arrangement the shafts with the parts mounted thereon may be readilymoved up and down in the slots.

Mounted on shaft 5 is a pair of outer yarn sticks supporting members or heads 10, 10,

`in opposed faces in' which are suitable brackets to support the yarn sticks 11. ivounted in suitable brackets 12.v 12 on the spokes 13 V13 of the outer stick support-A ing members is a pair of inner stick supporting members or heads one of which is shown at 14. The inner pai-'r of heads is also provided with means to support a series of yarn sticks 15, 15. The. yarn in the skein form is looped about corresponding sticks of the inner and outer series and in order to tauten the skeins, the stick supporting members are moved a short distance relatively to one another, thus increasing the distance between the corresponding sticks.

The shaft 5 with its attached members is now. lowered in the arcuate slot and upon rotation successive skeins are immersed in the dye liquor contained in the bottom of the vat, this liquor being suitably heated by steam introduced through a pipe 16. The usual trip and star wheel devices are provided so that the sticks will be given a stepwise rotation in their bearings upon the rotation of shaft 5 so as to insure the complete immersion and dyeing of all parts of the skeins.

The description so far relates to yarn dyeing machines of well known construction and is given here merely to make clear the operation of our improvement which, as stated, provides means for producing a relative adjustment of the stick supporting members, so as to tauten the yarn held thereon. Y

To provide such adjustment there is mounted on a suitable bracket 17, on one of the spokes of the outer yarn stick head, a shaft 18 provided with a squared head 19 at its outer end. At its inner end the shaft carries `a worm 20 meshing with a worm gear 21, mounted onl a shaft 21e, extending between the heads and supported in brackets 22 on the spokes. Rigidly mounted on the worm gear 21 is a crank arm 23 extending radially outwardly. If desired the crank 23 may be cast as an integral part of the gear 21. In is extremity the crank arm 23 has a slot 24 in which rides a pin 25 mounted on, or formed as an integral part of one of the inner yarn stick supporting members.

The construction above described is to be understood as mounted on a spoke of one of the outer yarn sup )orting heads but to insure that the heads of the inner series will be moved simultaneously so as to maintain the bearings for individual sticks in registry at all times, the shaft 21"L extends across the machine as indicated, Fig. 2, and is provided at its other end with a crank arm engaging a pin on the other inner yarn stick supporting member, the shaft being suitably supported on the other outer sujL porting member in a bracket corresponding to 22. By such an arrangement, the partial rotation of the shaft 21a by ineansof shaft 18, worm 20, and worm gear 21 will be transmitted by the crank arms to the two inner yarn stick supporting members simultaneously, and this movement relative to the outer supporting members serves to tauten the skeins. The shaft 1S may be turned by' means of a wrench or other suitable tool applied to the squared head and shaft 18 is turned in one direction to tauten the skeins and in the other, to loosen them so that the yarn may be freely removed from the machine when the dyeing is complet ed. On working the adjusting means set out in our patent aforesaid, the worm shaft and gearing multiply the force to tension the skeins, and after considerable experience with those devices it has been found that the proper tension can only with difficulty be closely determined, particularly in the somewhat hurried and more or less casual treatment of the machines in every day running. YVith the crank arm 23 and its operating contrivances, the machine attendant, even though he be not an old and trained dyer, soon learns by the sense of feeling to impress quickly upon the skeins the tension ascertained by practical experience to be demanded by any given kind or quality of yarn and the special dyeing process in hand. The extended crank arm on the pinion does not multiply the force applied, and the reaction felt by the operative is a much more practical and accurate guide to the proper tension.

It will be understood that the new and improved means by which thetwo yarn stick supporting members are moved relatively to one another, may be mounted in various ways and the construction is not limited to the exact arrangement shown. rlhe construction shown in the drawings is a convenient and perhaps preferable way in arranging the parts to perform the desired functions and it will be seen that a convenient means is provided for tautening the skeins with close adjustment of tension. Preferably the device is to be mounted on the outer faces of the yarn stick supporting` members as shown in Figure 2, in which posit-ion it can be readily operated without any danger of the operative coming in contact with the yarn. Furthermore, by extending the shaft 18 radially so that its squared end lies adjacent the periphery of the outer stick supporting member, the skeins may be tautened while the shaft 5 is in its lowered position. The device is construct-ed of simple elements which are not likely to get out of order and which will not readily wear to the point of inefectiveness.

lVhile the particular dyeing machine herein shown' is constructed so as to have its inner member supported in the outer member, it will be understood that the usefulness of the adjustment means is not limited to such a construction, being adapta-ble for use in any similar machine in which there are yarn sticks supporting members which must be moved relatively to one another to tension the yarn. It will be further understood that the adjusting' means is not limited to a machine in which there are but two inner and two outer yarnstick supporting members. It is possible, of course, to construct a machine in which there will be used heads intermediate the end heads, the intermediate yarn stick supporting head providing bearings on either face for yarn sticks. The adjusting means will be equally useful with such a machine as it is only necessary to continue the shaft 21a and provide additional cranks thereon to engage pins on all of the heads.

As many changes could be made in this -construction without departing from the scope of the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in alimiting sense.
